The purification of wastewater is usually accompanied by the release ofCO2. In the research project ACCeSS (Active Carbon Capture for Sustainable Synthesis) at Heinrich Heine University, RWTH Aachen University and Forschungszentrum Jülich, scientists from various disciplines have joined forces. Together, they are researching how wastewater streams can be treated with special red algae or cyanobacteria in such a way thatCO2 can be removed from the ambient air under the influence of sunlight and converted into valuable products. ACCeSS is organizing a panel discussion on the challenges and future of wastewater treatment in a fishbowl format. This allows all attendees to take turns playing the roles of panelists and listeners.
